[Risk assessment for development of sudden cardiac death in patients with progressive angina (based on results of 4-year prospective study)]. / Metody otsenki riska razvitiia vnezapnoi kardial'noi smerti u bol'nykh, perenesshikh progrssiruiushchuiu stenokardiiu (po rezul'tatam 4-letnego prospektivnogo nabliudeniia).

In a 4-year follow-up of those patients having survived progressive angina (PA), the incidence rate was estimated of development of sudden cardiac death (SCD), with the aid of the Caplan-Mayer method and that of life tables. SCD rate has come to be 21.4% and 7.2% in the main group and that of patients free from structural affection of the myocardium. It is during the first year of the follow-up that patients with prior PA were at the greatest risk for SCD. It has been ascertained that aneurysm of the left ventricle and presence of chronic I-II degree cardiac insufficiency are independent and significant risk factors for SCD in those patients with history of PA.
